My brother and I are close, and we share an apartment together on a college campus. When my brother masturbates, I have to help him because he isn't circumcised. When he masturbates, he has to pull down his foreskin before he strokes his cock. I hold down his foreskin for him while he strokes his cock. The area under the foreskin is very sensitive, so he moans a lot when he strokes his cock. He has a big cock. He also rubs the tip of his cock. He makes weird moaning sounds (ohhhhhhh, sssssssss). When he's close to cuming, he cries and says "my milk is cuming, my sperm is cuming." Before he squirts, he screams and says "ohhhhhh sis, my milk is cuming, ohhhhhhh, help me, my sperm is cuming. Then he squirts out his milk and says "ohhhhhhh, my beautiful sperm." He keeps stroking his cock until all his milk is out. My brother masturbates a lot. For his birthday, I'm going to buy him a cock ring (a cock ring is a ring used by uncircumcised men to hold down the foreskin during masturbation). That way he can masturbate without needing me to hold down his foreskin.
